I have a SLR Sony, and a SLR Fuji Is there adjustments I can set the lens to photograph my tree that is decorated in clear crystal ornaments and blue lights. and white lights to make a better pic.

The ornaments do not show up and the tree looks like it is not decorated in the pics.

You need to use Exposure Compensation. The dark tree fools the camera. Google that term, would take a while for me to explain here. Gene
